Dirty Sensor warning and Active Brake Assist lamp on
Started yesterday, the dirty sensor warning message came on, then active brake assist warning light stayed on. The dirty sensor warning indicated the drive assistance functions may be affected. I cleaned the most of the sensors under front bumper as user's manual suggested, but warning is still there.
The interesting observation is that the warning doesn't come on right way when started the car, it shows up after 5-10 minutes of driving. It drives fine. It seems that all the drive assist functions are OK (adaptive cruise control, lane departure warning, intelligent recuperation etc.). Only lane change assist seems problematic.
I made an appointment to have the dealership looked at next week.

Some of us have had these minor glitches which seems in many cases to resolve themselves when the EQS is locked and you walk away from it for 20-30 minutes.
